I was taught that 1 cheval-vapeur = 75kgm/s which is:

75/0.454/0.3048*60= 32,519.3382 ft*lb/min

Much later, I read (I think it was in New Scientist), that
a horse has a power closer to 12hp, early automotive
manufacturers having deliberately grossly underrated a
horse's strength to sell their wares.
